Compliance overview
Scope and applicability
This standard applies to the calculation of lost workdays and the rapid determination of minor or severe injuries for injured personnel during work safety accident investigations in China. It covers various types of occupational injuries including trunk and limb damage, eye, ear, nose, throat, and internal organ injuries, as well as occupational acute poisoning and burns. It is explicitly not applicable for calculating actual missed work time, hospitalization duration, work suspension periods, or work-related injury insurance compensation amounts. The standard also applies to non-employees and individuals without employment, such as the elderly or children, if they are injured in a production safety accident.
Technical requirements
The standard establishes the fundamental requirements for injury assessment, dictating that evaluations must be based on diagnostic results issued by secondary or higher medical institutions within 7 days of admission. It introduces specific calculation methodologies for multiple injuries, distinguishing between 累积伤害 (accumulated injuries to functionally related body parts) and 共存伤害 (coexistent injuries to functionally unrelated body parts). The final calculated lost workdays for any injured person shall not exceed 6000 days, which is the fixed value for fatalities. It categorizes injury loss workdays across detailed anatomical and physiological systems. This includes parameters for trunk and limb fractures, joint and soft tissue damage, limb amputations, and neurological damage. It also specifies ranges for specialized injuries such as visual impairments, hearing loss, maxillofacial trauma, acute craniocerebral injuries, and internal organ damage (e.g., thoracic, abdominal, urogenital). Furthermore, it outlines assessment criteria for 职业急性中毒 and various degrees of burns (including thermal, chemical, and electrical burns) as well as frostbite. A critical addition in this revision is the 结果应用 (Result Application) chapter, which sets the threshold for injury severity classification. Injuries resulting in less than 105 lost workdays are classified as minor injuries, while those resulting in 105 or more lost workdays are classified as severe injuries. It also provides direct severe injury determination criteria for emergency situations, such as when a patient is admitted to the Intensive Care Unit.
Testing methods
The standard does not involve traditional laboratory testing methods; instead, its evaluation procedures rely on medical diagnostic verification. The assessment requires clinical diagnostic evidence, including outpatient and inpatient medical records, pathology reports, blood tests, and imaging reports. For complex cases where clear diagnostics cannot be issued within 7 days or for injuries not explicitly listed in the standard, an evaluation must be conducted by organizing a medical expert panel to reference the closest applicable clauses. The calculation procedure involves identifying the specific injury type, matching it to the corresponding conversion table in Appendix A, and applying the prescribed mathematical formulas for accumulated or coexistent injuries to derive the final lost workday value.
FAQs
What is the primary scope of application for GB 15499-2025?
It applies to the calculation of lost workdays and the rapid determination of minor or severe injuries for injured personnel during work safety accident investigations. It is important to note that it does not apply to calculating actual lost time, hospitalization duration, or work-related injury insurance compensation amounts.
Are there any significant updates from the previous GB/T 15499-1995 version?
The 2025 version is a mandatory standard replacing the recommended GB/T 15499-1995. Key updates include the addition of basic requirements, updated terminology, revised loss workday ranges for various injury types (such as 躯干 and limb injuries), and the introduction of a rapid assessment method for determining 轻伤 and 重伤 in emergency situations.
How does GB 15499-2025 define "lost workdays" and does it reflect actual missed work time?
The standard defines lost workdays as a quantitative time metric representing the severity of human injury. This metric is used specifically to classify the severity of an accident rather than to reflect the actual number of days an employee is absent from work.
